Description
Technical Field
The invention belongs to the technical field of pipe fittings, and particularly relates to a double-pass cock type valve.
Background
A plug valve is a valve which is a closing member or a plunger-shaped rotary valve and is opened or closed by rotating 90 degrees so that a passage opening on the valve plug is identical to or separated from a passage opening on a valve body. The plug of the plug valve may be cylindrical or conical in shape. In a cylindrical valve plug, the passageway is generally rectangular; whereas in a conical valve plug the channel is trapezoidal. These shapes make the structure of the plug valve light, but at the same time create a certain loss. Plug valves are best suited for use as both a shut-off and a shut-on medium and as a shunt, but are sometimes also useful for throttling depending on the nature of the application and erosion resistance of the sealing surfaces.
The plug body with a through hole is used as a valve of the opening and closing piece, and the plug body rotates to realize the opening and closing action. Small, non-filled plug valves are also known as "cocks". The plug body of the plug valve is mostly a cone (also a cylinder) and is matched with the conical hole surface of the valve body to form a sealing pair. The plug valve is the earliest valve used, and has simple structure, rapid opening and closing and small fluid resistance.
At present, the cock valve in the prior art only has one valve body, and for complex pipeline conditions, a plurality of cock valves are connected in parallel, so that the requirements of the cock valve can be met, but the sealing performance of a single cock valve is general, if a plurality of cock valves are connected in parallel, the sealing performance is further reduced on the whole, meanwhile, the occupied volume is large, and each cock valve is manually and respectively adjusted, so that the cock valve is inconvenient.
Disclosure of Invention
In order to solve the technical problems in the prior art, the invention provides a double-pass cock valve which is provided with two valve bodies, and meanwhile, the sealing performance of the cock valve in the prior art can be maintained or improved, and the double-pass cock valve is reasonable in structure and convenient to use.
The invention solves the technical problems by the following technical proposal:
the utility model provides a two-way cock type valve, includes first valve body, second valve body, gland, first cock and second cock, first valve body passes through the seal shell and is connected with the second valve body to be placed in the second valve body top, the gland is installed on first valve body, and the bottom is equipped with the packing, first cock passes the gland until the bottom of first valve body, the part that first cock is located the packing lower part is first plug head, first plug head comprises two first cock flaps that are symmetrical to first cock central line, be equipped with first opening between the first cock flaps, the second cock passes first cock until the bottom of second valve body, the part that the second cock is located the second valve body is the second plug head, the second plug head comprises two second cock flaps that are symmetrical to second cock central line, be equipped with the second opening between the second cock flaps.
As a further improved technical scheme, the first valve body and the second valve body are arranged in parallel.
As a further improved technical scheme, the outer surface of the upper part of the first cock is provided with a first rotating disc, and the outer surface of the upper part of the second cock is provided with a second rotating disc.
As a further improved technical scheme, the thickness of the first plug valve gradually decreases from top to bottom, and the thickness of the second plug valve gradually increases from top to bottom.
As a further improved technical scheme, the top of the second cock is 1-3cm higher than the top of the first cock, and a sealing ring is arranged at the joint of the top of the first cock and the second cock.
As a further improved technical scheme, in the vertical direction, the central axis of the first cock, the central axis of the second cock and the central axis of the gland are coincident.
The beneficial effects of the invention are as follows:
Compared with the prior art, the plug valve provided by the invention comprises two valve bodies, and can greatly reduce the number of the valve bodies connected in parallel according to complex pipeline conditions, so that the sealing performance is maintained or improved on the whole; meanwhile, due to the structural characteristics of the valve body, the sealing performance of the valve body is kept or is superior to that of a cock valve in the prior art although the valve body is provided with two valve bodies; simple structure, rational in infrastructure, working volume is little, and occupation space is little, and the workman of being convenient for operates and uses, also is convenient for arrange pipeline etc. simultaneously.
